BGP that is used to routewithina single AS is iBGP. When BGP is used to connect one AS to others, it is called External BGP, or eBGP. The Open Shortest Path First (OSPF) protocol is used only in internal networks. OSPF focuses on finding the shortest route available between nodes and ...
BGP is designed as an inter-domain routing protocol with the goal of policy control and scalability. However, BGP cannot replace IGP because they apply to different scenarios. BGP is called Internal BGP (IBGP) when it runs within an AS and is called External BGP (EBGP) when it runs between...

Routes learned from EBGP peers are advertised to other BGP peers, including both EBGP and IBGP peers. Routes learned from an IBGP peer are not advertised to other IBGP peers. The advertisement of routes obtained from an IBGP peer to EBGP peers depends on the BGP-IGP synchronization state. Aft...
Therefore, BGP can be divided into interior BGP (IBGP: connection between the same AS) and EBGP. (Exterior BGP: BGP connection between different ASs) Since EGP has been replaced, EBGP is easy to understand, but IGP is still alive and well (OSPF here). What is the significance of IBGP?
Bidirectional Forwarding Detection is used with many protocols for link failure detection. These protocols are: Static routes IGPs (OSPF, IS-IS) BGP (eBGP, iBGP) LDP RSVP Disadvantages of BFD Beside the advantages of BFD, it has also some disadvantages. First of all it can have more resource...
